Multiple minute digitate hyperkeratoses: a case report.


Multiple minute digitate hyperkeratoses (MMDH) is a rare familial or acquired cutaneous eruption of filiform keratoses, typically across the trunk and extremities. Histopathology, distribution, and history can distinguish it from other digitate keratoses. We describe a case of MMDH and discuss it in relation to other disseminated digitate keratoses.
